Hi CodeCat! We have a user who has been adding Goguryeo terms. I suggested to Ruakh that if they aren't valid because they are reconstructions, perhaps they could be added to an appendix. Ruakh said that they appear to be a single scholar's reconstructions, rather than something generally accepted, and said I should check with you for your opinion, given that you have more experience in this sort of thing. I have started a conversation at Wiktionary:BP#On_Goguryeo and would appreciate any input you have! Best regards.
I should have been more specific. The issue is about putting reconstructions, and specifically, reconstructions made by a single scholar into an appendix and/or allowing them in the main namespace? Also of interest is that these terms are being added as Chinese characters--if these are reconstructions, then applying Chinese characters seems valid, if shaky.
